Created attachment 116249 [details] The build process
I just stumbled on the same problem. Running "java-check-environment" showed that I had only jdk-1.5 installed. Running "emerge '=virtual/jdk-1.4*'" fixed the problem.
Well, thanks for the advice, but that way it'll install jdk 1.4 and I think that I'm not supposed to have all versions of java in order to run any single program. Every VM is supposed to be compatible with older versions. To me jdk 1.5 and 1.6 are more than enough on a single machine.
Unfortunately I'm not really a specialist on java. The error from java-check-environment looks to me as if a pre-1.5 jvm is required for some applications. The must be a reason why java-check-environment checks for a "generation 1 vm" and then recommends installing jdk 1.4.

Thank you both, I'll just use the java overlay, rather than installing another jdk on my hdd.
